The wilderness can be frightening if we got lost, our supplies run low or our gear disappears. How do we find food and water, how do we make fire, how do we find our way back and how do we stay warm at night? What about those wild animals out there and the weird sounds at night? It's the fear of the unknown that can creep into our mind before the adventure begins. Knowledge and experience are the first step to overcoming fear. Self-assurance and pre-prep are cognate.
